Purpose: In 2002 Portland created guidelines to encourage variation in the width of lots to maximize solar access for single-dwelling detached development and minimize shade on adjacent properties.
Inclusion: The following applies to lots for single dwelling detached developments created as part of a land division in all zones. Where it is not practicable to meet both the approval criteria of chapter 33 and the standards and approval criteria of other chapters in the 600’s, the regulations of the other chapters supersede the approval criteria of this chapter.
Solar Access Approval Criteria:
All the following must be met:
A. On streets that are within 30 degrees of a true east-west axis, see Figure 639-1, the narrowest lots should be:
- Interior lots on the south side of the street. See Figure 639-2; and
- Corner lots on the north side of the street. See Figure 639-3.
B. On streets that are within 30 degrees of a true north-south axis, the widest lots should be interior lots on the east or west side of the street. See Figure 639-4
